I opened the coop this morning and found one of my lav. orp. chicks dead on the floor. All of the others were perfectly fine. It got down into the low 20s last night, but there is a heat lamp in there. I went out to check on them late last night and all of them were acting normal. Their run does have fallen acorns and possibly pecans. Could that have caused it to die? I am so puzzled as to what could have happened. They are 2 months old. Thanks in advance for any help.
